April 5,1932- T. A. GREEN RENEWABLE SURFACE DUST CLOTH 'Filed Dec. 27,1929 Patented Apr. 5, 1932 THORNTON A. GREEN, OF ONTONAGON, MICHIGANRENEWABLE SURFACE DUST CLOTH Application filed December 27, 1929. SerialNo. 416,8),1.

This invention relates to dust cloths and more particularly to a paperdust cloth having a plurality of fresh cleaning surfaces which aresuccessively available by stripping off the outermost one.

It has been more or less customary in this art to utilize dust'cloths offabric or dust cloths having only a single cleaning surface so that whenthe surface is soiled from use the dust cloth must either be discardedor washed, or refolded to expose-a partiallyclean surface but in each ofthese cases economy is not secured and the dirt or grease which isremoved from the surface being cleaned is very likely to be rubbed intothe next portion of the surface or another surface being treated so asto manthe same or result in an ineflicient cleaning of the same. Thesedisadvantages are all eliminated by the present invention whichadditionally pre sents advantages of its own peculiar to its nature andcomposition.

In a general way, the present dust cloth is composed of a comparativelythick body of loosely matted fibers arranged in a number of very thinsuperposed layers each of which readily separates from the under-lyinglayers merely by stripping off the same. In this way a dust cloth of agiven size can be utilizcii very economically and for a' much greatersurface or area to be cleaned even than a plurality of dust cloths ofthe known types, and as each outermost layer becomes soiled a freshunder-lying layer canbe readily made available by simply stripping offthe outermost soiled layer. In addition the dust cloth may be andpreferably is impregnated with any suitable or desirable wax or ,oil orthe like for the usual purposes.

The drawing illustrates a perspective view of a preferred embodimentofthe invention,

several of the layers being partially turned.

backto show more clea'rly'the manner in which the dust cloth is made.

' Referring now particularly to the drawing in detail the dust cloth isindicated in its,

entirety by the numeral 10. The dust cloth may be of any appropriatesize and shape and the particular embodiment shown is apsurface beingcleaned or dusted. 'avcon dition is reached the soiled layer can readilybe picked up at one of its corners by proximately twelve inches inlength and of about the same width.

The material of the dust cloth is, as has already been stated, paper andcomposed of a plurality of superposed and meshed thin fibrousloosely'compacted layers 11. -Each layer is relativelyvery thin andabsorbent due to its loose texture which may be called anincompleteunsized paper web. The dust cloth may be formed by rolling into a largeroll a considerable length of the loosely compacted fibrous web and fromthe large roll thus formed portions of suitable size and thickness maybe cut out to any desired de th of material, thereby determining the numer of layers in a given dust cloth and hence the number of freshcleaning surfaces.

Each dust cloth may thus consist of a number of thin layers and inpractice the number of layers may run anywhere from a comparativelysmall number as 5 or 6 to a comparatively large number say 25 or '50 oreven more. y

The loosely compacted fibrous web may be impregnated with a wax or oilat any desired stage in its formation but one convenient manner ofimpregnation has been found to-be that of spraying or atomizing the oilor wax in a liquid condition onto the paper Web as it comes from theforming roll. It is clear however, that the impregnation could beperformed at other points in the formation of the dust cloth-as byincorporating the materials in the vat or Jordan machine in which thepulp is mixed or even by exposing the dust cloths or rollsof fibrousmaterial before they are cut into dust cloths to the vapors or otheraction of the wax or oil under suitable conditions, i i p In use, a dustcloth' say of approximately 12 by l2inches is manually manipulatedoverthe surface to be cleaned such as that of furniture, automobiles,floors, glass or the like until the outermost surface which is beingutilized for the cleaning operation is relatively dirty or soiled sothat its "further'use would be inefiicient or even detrimental to theWhen such the fingers and stripped off leaving exposed therebeneath aclean surface immedlately ready for use. When this next layer is simi'larly soiled it may be stripped oil as was the first layer and thecleaning operation may be continued if desired until the dust cloth hasbeen fully utilized or when the remaining layers become very few innumber they may be readily added to another dust cloth of similar kindmerely by super osing them thereon, whereupon the loose brous structureof one layer will in a measure adhere to the loose fibers ofthe'adjacent layers. In this manner there is no waste of material un-,der any circumstances and the cleaning operation can proceed withoutinterruption.

A given thin loosely compacted web may be rolled into a large roll ofconsiderable length in order that the loosely compacted fibres of eachof the layers of the web thereby formed will intermeshhnd cling to thefibres of adjacent layers to form a loosely compacted but composite rollof polishing orodust cleaning material. To obtain a dust cloth of adesired length, width or depth, a. lanar section is cut across said rollto a dep responding to a desired number of layers of compacted webs.

These dust cloths can be made exceedingly cheaply so as to be Widelysold or dispensed at a nominal price and moreover the soiled layers arevery easily disposed of and if desired a water soluble paperifiber maybe used tlzhereby aiding the ready disposal ofthe soiled ayers. v

It has been found in practice that such a dust cloth as I have abovedescribed is very easy to utilize and the absorbent nature of the layersenables a relativel great amount of soiled matter to be heldjlntherloosely compacted fibers; The advantages'are great and the dustcloths may be shaped to fit the hand and in any desirable shape so as tofacilitater their use.
